Benchmark recommendations needed

[Andras Tantos <andras@tantosonline.com>]

Hello all!

I'm working on porting GCC to a new processor architecture. I think
I've finally got to a fairly stable stage, so the next logical step
would be to test and optimize. For that, I would need some benchmarks,
and this is where I'm seeking your help.

This being a hobby project, I can't shell out $1000+ for the spec
suite. On top of that, I only have newlib ported as the runtime, which
means very limited support for OS facilities.

I already have dhrystone, but what else would you recommend using?

I'm looking for 'general purpose' payloads, things, where I can judge
object code size, instruction set utilization, look for tuning
opportunities, etc.

I would like to also be able to compare the results with other
architectures (FPGA cores, such as nios2 as well as some low-end cores,
such as 32-bit arm/thumb and riscv-RV32IMFC).

So, can you suggest some benchmarks or applications to be used as ones?

Thanks a bunch!
Andras
